我想用JSF發送電子郵件。我創建了成功發送電子郵件的頁面，但是當我從主菜單動態調用此頁面時，它會出現在我的頁面中心，但有些框不會顯示，最糟糕的是：Bean根本不工作。 所以我的問題是我應該如何正確地包含此頁面，以便仍然使用Beans的所有功能，或者如何從此頁面調用bean。 注意：它工作，只是在主頁內停止。通過ui包含頁面的觸發bean方法：include
因爲我也有問題直接調用我的Bean的sendMail2（）方法，此刻我調用setter的屬性（因爲它的工作原理），並且在這個setter方法中我調用了sendMail2（）。

在這裏我如何渲染菜單：

什麼'helloBean.name'的價值？ – 2013-04-09 22:21:41
它是子頁面的名稱，即zapytaj.xhtml – 4pie0 2013-04-09 22:22:27
我看到沒有任何反應，當我點擊這個子頁面的按鈕時：SendBean沒有被調用，但是當頁面打開時工作單一，主要 – 4pie0 2013-04-09 22:25:00
